As im sure some of you have seen, there are some incredibly busted characters in the game, which is why I propose a nerf to some of them
XEvent -
One of the obvious examples, Cross can shred your health in first phase very easily, and have survivability to boot. Along with the fact with only one well timed hit or perfect block, he can start an insane combo, which can get quite..annoying. One idea to nerf him is by changing Knife 1 to not hit a downed opponent, or changing how fast Normal 2 can be used. XChara is a bit more reasonable in power, the only problem I can actually foresee is Overwrite 5 being busted, and Normal 1 being too loud and obnoxious for other players
US Sans -
Underswap Sans is quite busted as well, mainly due to how long his dodging phase can last and how he can regen mana, along with a slew of spammable moves. The best I can say is to lower US Sans' mana in dodging, but lower it when hit
Player -
UnderPlayer can have some high damage combos, like really high. The only thing I can really think to say is increase the cooldown of Normal 1 slightly and reduce the damage of Phantom Blade very slightly. But aside from that, her Blasters should receive a better hitbox to encourage people to use it in combos
And thats it, feel free to leave constructive criticism in the comments
